中新网评：处理核污水绝不是日本自家私事******
中新网北京1月19日电(蒋鲤)日本政府近日称，将于2023年春夏期间开始向海洋排放经过处理的福岛第一核电站核污水。日本罔顾国内民众及周边国家的屡屡反对，企图将核污水“一倒了之”，把一件关乎全球海洋生态环境和公众健康的事当成了自家私事。
资料图：日本福岛第一核电站。2011年，福岛核电站事故发生后，大量放射性物质泄漏到大气层和太平洋，对周围环境造成了难以逆转的伤害，数十万人被迫撤离该地区。时至今日，作为日本邻国之一的韩国仍未解除福岛海鲜禁令。
日本以核污水存储能力即将达到上限为由，在2021年4月13日，正式决定将福岛第一核电站核污水排入太平洋。过去一年多，日本政府和东京电力公司一直在持续推进核污水排海计划。
日本政府辩称，这些核污水经多核素处理系统(ALPS)处理后很安全，甚至“可以喝”，这样的表态无疑在愚弄大众。
事实上，经过处理的核污水仍含有多种放射性物质，核污水一旦排放入海就无法回收，长期来看，将会给海洋生态带来难以估量的潜在威胁，最终危害人类健康。
因此，核污水排海计划推出后，遭到日本民众强烈反对。日本《朝日新闻》2022年3月公布的问卷调查显示，福岛县、宫城县和岩手县受访的42个市町村长中，约六成反对东京电力公司福岛第一核电站核污水排放入海。日本全国渔业协会联合会也多次申明立场，反对该计划。
日本政府认为，核污水排海是最便宜、最省事的解决方案，但此举却将周边国家乃至全世界置于核污染风险中。太平洋非日本一家之海，核污水会随着洋流流动，其影响势必会跨越国界，危害周边国家乃至整个国际社会的公共福祉和利益。
《韩国经济新闻》发文称，相关研究认为，福岛核污水如果排放入海，约7个月后将到达济州等韩国海域，该国水产业和旅游业将遭受相当大的损失。
德国南极海洋机构也曾发出警告，若日本将所有核污水排入海中，不到半年，整个太平洋都将面临高度辐射威胁，包括远在大洋另一端的美国。太平洋地区人民更是对日本该计划持反对意见。
日本作为《联合国海洋法公约》缔约国，有义务保护海洋环境。然而，在核污水排海方案的正当性、核污水数据的可靠性、净化装置的有效性、环境影响的不确定性等问题上，日本未能作出科学、可信的说明。
国际原子能机构技术工作组虽已三次赴日实地考察评估，但尚未就日排海方案的安全性给出结论，并且对日本提出诸多澄清要求和整改意见。在此情况下，日本仍执意推进核污水排海工程建设，这是极不负责任的行为。
太平洋不是日本的下水道，日本必须正视各方合理关切，在与周边国家等相关利益方和国际原子能机构充分协商后，制定合理的核污水处理方案。日本也要着眼长远，若只顾眼前，执意将核污水排放入海，不仅其自身，周边国家乃至全世界都将为之买单，其后果必将会危害数代人。
Fukushima water disposal by no means Japan’s own business
By John Lee
(ECNS) -- Japan has announced it will release treated wastewater from the wrecked Fukushima Daiichi Nuclear Power Plant into the Pacific Ocean this year.
Although Fukushima wastewater disposal affects global marine ecological environment protection and public health, Japan has turned a deaf ear to domestic and international opposition to dumping the contaminated water into the sea, treating the "global" matter as its own business.
The Fukushima accident in 2011 had sent large quantities of radiation into the atmosphere and the Pacific Ocean, causing irreversible damage to the surrounding environment, and hundreds of thousands of people were forced to evacuate the area. South Korea still maintains its import ban on Japanese seafood from areas affected by the Fukushima nuclear disaster.
On April 13, 2021, Japan announced it had decided to discharge contaminated radioactive wastewater in Fukushima Prefecture into the sea due to dwindling storage space, with the Japanese government and plant operator Tokyo Electric Power Company Holdings Inc. promoting the release plan over the past year.
The Japanese government argues that the water treated by an advanced liquid processing system, or ALPS, is safe and drinkable, which is undoubtedly fooling the public.
In fact, the treated wastewater still includes a variety of radioactive substances and can’t be recycled once discharged into the sea, which will pose a great threat to marine ecology and ultimately endanger human health in the long run.
Therefore, the discharge plan has been strongly opposed in Japan. According to a questionnaire conducted by The Asahi Shimbun, nearly 60 percent of mayors of 42 municipalities in Iwate, Miyagi and Fukushima prefectures oppose the discharge plan. The National Fisheries Cooperative Federation of Japan has also repeatedly stated its opposition in public.
The Japanese government believes that dumping Fukushima wastewater into the sea is the cheapest and most convenient solution, but neighboring countries and even the whole world will be at risk of nuclear pollution.
The Pacific Ocean doesn’t belong to Japan and the wastewater flow along oceanic currents will surely break boundaries and endanger public welfare and the interests of neighboring countries and even the international community.
The Korea Economic Daily reported that related research concluded that if contaminated water from Fukushima is released into the ocean, it would only take seven months for the contaminated water to reach the shores of Jeju Island, with the country's aquaculture and tourism suffering considerable losses.
According to the calculation of a German marine scientific research institute, radioactive materials will spread to most of the Pacific Ocean within half a year from the date of discharge, and the U.S. and Canada will be affected by nuclear pollution. People in the Pacific region also oppose the discharge plan.
As a participant of the United Nations Convention on the Law of the Sea, Japan has the obligation of protecting the marine environment.
However, it hasn’t offered a full and convincing explanation on issues like the legitimacy of the discharge plan, the reliability of data on the nuclear-contaminated water, the efficacy of the treatment system or the uncertainty of environmental impact.
Though the IAEA has yet to complete a comprehensive review after three investigations in Japan, the Japanese side has been pushing through the approval process for its discharge plan and even started building facilities for the discharge. It is rather irresponsible for Japan to act against public opinion at home and concerns abroad.
The Pacific Ocean is not a private Japanese sewer. The country must seriously heed the voices of the international community and make a reasonable plan for the Fukushima wastewater disposal after full consultation with stakeholders and international agencies.
If it only seeks instant interest and insists on discharging the contaminated water into the sea, not only itself, but also its neighboring countries and the entire world will pay for the decision and several generations will be forced to bear the consequence.
四川眉山发现成都平原迄今最早旧石器时代遗址****** 中新网成都1月10日电 (记者 岳依桐)10日，“遂宁市桃花河遗址暨四川旧石器时代考古成果专家研讨会”10日在四川射洪举行。会上透露，眉山新发现一处成都平原迄今最早的旧石器时代遗址——坛罐山遗址。根据光释光测年，初步推测该遗址最早遗存年代距今不低于20万年，填补了成都平原旧石器时代的考古空白。 据介绍，坛罐山遗址位于眉山市东坡区多悦镇滴水村与太和镇马堰村交界处，地处成都平原南部、岷江支流东醴泉河右岸的低缓垅岗上。2019年12月，为配合当地基本建设，四川省文物考古研究院联合眉山市文物保护研究所、眉山市东坡区文化遗产保护中心等单位在坛罐山开展考古调查工作，调查发现一件打制石核及其他文化遗存，在此后的考古发掘中，共出土石制品518件，清理坑、沟等遗迹现象10余处。 经专家确认，该遗址出土石制品大多以砾石为原料，岩性以石英砂岩为主。石制品类型包括石核、石片、断块/断片/碎屑、工具、备料。工具类型除石锤和石砧外，还有砍砸器、刮削器、凹缺刮器、锯齿刃器、重型刮削器、手镐等，另外还有使用过的砾石以及石片。工具多以砾石或断块为毛坯，采用锤击法加工，多见单边、单向修理，整体上属于中国南方砾石石器工业的范畴。  考古发掘现场。 四川省文物考古研究供图专家认为，坛罐山遗址是一处典型的中国南方砾石工业类型遗址，出土石制品与简阳龙垭遗址、资阳鲤鱼桥遗址、重庆铜梁遗址等在石器组合、剥片技术等方面大体相似，石料、石器类型和技术上也较为一致，均属于典型中国南方砾石工业传统。坛罐山遗址也是一处古人类多次光顾、短期活动的原地埋藏遗址，它的发现与发掘，将逐渐揭开成都平原古人类与旧石器时代考古文化的面纱。 中国旧石器考古专业委员会主任高星表示，坛罐山遗址进一步为四川盆地的旧石器时代考古工作提供线索、导向和思路。通过对坛罐山遗址的发掘、梳理、认知，考古工作者已在成都平原新发现了140余处旧石器时代遗址，其中已开展考古发掘的遗址近10处，为下一步构建成都平原乃至四川盆地旧石器年代框架、完善工业体系奠定了坚实的基础。(完)
